Thermoplastic resin composition |
(57) A thermoplastic resin composition well balanced among heat resistance, high-impact
properties and moldability is provided, which composition comprises 50 to 90 parts
by weight of a random copolymer (A) composed mainly of a-methylstyrene units and acrylonitrile
units, 0.2 to 1.0 part by weight based on 100 parts by weight of the random copolymer
(A), of an oligomer (B) composed mainly of a-methylstyrene units and acrylonitrile
units and having a molecular weight of 200 to 500 and 10 to 50 parts by weight of
a dien rubber-aromatic vinyl monomer-vinyl cyanide graft copolymer (C).
